Abstract
The present invention provides a disc clamp for use with a disc stack assembly where the disc stack assembly is designed for rotation about an axis. The disc clamp includes a set of openings defined by a body, such that each opening has line symmetry about a line of reflection that intersects the axis. The disc clamp also includes a set of flanges, each which extends from the body into one of the openings. The disc clamp is made such that the set of openings has rotational symmetry about the axis and the set of flanges is rotationally asymmetrical about the axis.
